UFC officials announced the change on Tuesday. MMAJunkie.com earlier reported that
Drysdale was flagged by the Nevada Athletic Commission for an
elevated testosterone-to-epitestosterone (T/E) ratio, and
Sherdog.com verified with NAC Executive Director Keith Kizer that
the light heavyweight was not approved to compete by the regulatory
body. Kizer confirmed that Drysdale produced a T/E ratio of 19.4-1,
more than three times Nevada’s allowable limit of 6-1. It is
unknown at this time if Drysdale will face a disciplinary hearing
at the commission’s next meeting.

Villante, 28, posted three straight wins to close out his
Strikeforce career after suffering a unanimous decision defeat to
Lorenz
Larkin in his 205-pound debut, besting Keith Berry,
Trevor
Smith and Derrick
Mehmen before falling to “The Monsoon.” The New Yorker last
competed on April 27, when he saw his momentum halted in a
controversial, technical-decision defeat to Ovince St.
Preux at UFC 159.

Donovan, 32, also faced St. Preux in his last in-cage appearance,
though “Donnybrook” was knocked out by “OSP” in just over two
minutes this past August at UFC Fight Night 26. The light
heavyweight had won four straight fights prior to that defeat,
making his Octagon debut last December with a first-round knockout
of Nick
Penner at UFC on FX 6.
